ADJUSTABLE FUNNEL.

SPECIFICATION forming part of Letters Patent No. 427,874, dated May 13,1890.

Application filed July 2, 1889- Serial No. 816,354. (No model.)

To all whom it may concern.-

Be it known that I, JOSHUA JONES, residing at Auburn Park, in the countyof Cook and State of Illinois, and a citizen of the United States, haveinvented a new and useful I1nprovcment in Adjustable Funnels, of whichthe following is a specification, reference being had to theaccompanying drawings, in which- Figure 1 is a side elevation of myimproved funnel, showing also a vial attached to the funnel in positionto be filled. Fig. 2 is a vertical section of the parts shown in Fig. 1.Fig. 3 is a top view of the retaining-ring. Fig. 4 is a view of theblank from which the funnel is formed, showing also secured thereto thenotched strips which hold the ring, and the hook for retaining the upperedges of the overlapping portions of the funnel in contact with eachother.

This invention relates to funnels used for filling small vials orbottles with powders, and has for its object to provide an adj ustablefunnel that can be used with vials or bottles of various sizes and inall cases leave the mouth of the bottle entirely unobstructed, so thatthe bottle can be quickly and readily filled; and its nature consists informing the body of the funnel of a single piece of thin sheet metal orother suitable material bent over and its edges lapped but not soldered,and in providing a holding-ring which is slipped over the smaller end ofthe device and held in position by notches formed in strips attached tothe outside of the funnel, as illustrated in the drawings andhereinafter fully described.

That which I claim as new will be pointed out in the claims.

In the drawings, A represents the body of the funnel, which is to beformed of thin sheet brass or steel or other suitable material. It is tobe cut or stamped in substantially the form shown in Fig. 4, so thatwhen bent into funnel shape the edge a will lap over the edge I), andthe notch 0 (shown in said Fig. 4) will form the discharge-opening ofthe funnel.

B are strips of metal suitably secured by rivets or otherwise to theouter surface of the funnel A, as shown. They are to be so located as tobe opposite to each other, or nearly so, when the funnel is ready foruse. Each strip is provided with a number of notches e, as shown.

C is a metal ring of. suitable size to encircle the lower portion of thefunnel-body A.

(Z is a flat hook suitably secured to the funnel-body A in such positionthat the hook will project over the upper edge of the funnel, the hookend being wide enough to permit it to engage two thicknesses of thematerial from which the funnel-body is made.

To form the funnel the blank shown in Fig. 4:, with the strips I3 3 andhook d thereon, is bent over and the edge a lapped over the edge I), andthe upper edge of the under portion caught under the hook (I, whichholds the lapping portions in close contact with each other. The ring Gis to be then slipped on from the lower end and caught in a notch e ofeach strip B, which will retain the body A in funnel form.

In use the discharge-opening is to be left large enough for the neck ofa bottle to be inserted therein. After it is inserted the body A is tobe compressed, so that the edge of the discharge-opening is pressedtightly against the neck of the vial. The ring 0 is to be raised whilethe body A is still compressed and placed in such of the notches c aswill retain the' body A in the position into which it has beencompressed by hand. The Vial will be prevented from slipping out by thecontact of its lip with the inside of the funnel. The powder intended tobe placed in the vial can then be poured into the funnel, from whence itwill pass to the vial without any obstruction in the neck of the vial.After the vial has been filled the funnel can be detached therefrom byslightly compressing the funnel where it is encircled by the ring 0,when such ring can be placed in some of the lower notches, which willallow the body A to spring enough to enlarge the discharge end andrelease the vial.

By means of the ring 0 the size of the body of the funnel can beincreased or decreased whenever desired in order to adapt its dischargeend to fit different sizes of vials, and in all cases a close fit iseffected between such discharge end and the vial to be filled, and theinterior of the funnelis kept smooth, as the hook cl, projecting overthe upper edge of the interior lapping portion, keeps such interiorlapping portion in close contact with the other lapping portion.

By slightly compressing the funnel, as before described, the ring 0 canbe readily 5 slipped off, which will allow the body A to straighten outor spread open, in which position it can be more readily cleansed andp01- ished than when in the funnel form.

The funnels ordinarily employed for filling 1o vials are provided withspouts, which are inserted in the necks of the vials, and thus narrowthe space in the neck, which is an objection in very small Vials. By theuse of my hat I claim as new, and desire to secure by Letters Patent, isas follows:

1. A funnel consisting of a single piece of sheet metal or othersuitable material, the edges of which are overlapped but not joined, incombination with notched strips 1:3, adapted to retain a ring 0,substantially as and for the purpose specified.

2. A funnel consisting of a single piece of sheet metal or othersuitable material, the edges of which are overlapped but notjoined, incombination with notched strips 13, adapted to retain a ring C, and ahook (I, substan tially as and for the purposes specified.

JOSHUA JONES.
